Ok well that makes sense, and as this is the second time I've run up credit card debts whilst buying a property I'm not sure that my promise not to run them up again is going to work, but I am co-buying this time and would be way more mindful of my debts affecting other people, plus I am definitely going to cut the bloody things up!! I suppose some deposit is better than nothing and I'd rather have no credit card debts if I possibly can, and I hadn't thought about the interest rate thing, so thankyou for the advice!!
